Re: patch for gtk+-2.0 : support for new Application Launch Feedback mechanism

[Mary Dwyer <Mary Dwyer Sun COM>]

hi

There are problems with your proposal as I understand it:

1. The launcher would:
      - start the feedback display 
      - fork and exec application
      
      But, if the feedback display window is awaiting an X client 
      message then it would have to use gtk_main(). Therefore, the
      start_feedback() would not return to allow launcher to fork and 
      exec the application. (In galf the feedback display window just
      uses gtk_widget_show()).As far as I can see, you would have to use
      threads to get around this ......
      
      
2.  The mechanism you propose relies on the toolkit being compliant (ie
    sending the X client message). The galf mechanism has a workaround
    for non-compliant toolkits (ie toolkits that do not set the 
    _NET_WM_LAUNCH_ID property), in that it monitors for the mapping of a new
    window that does not have that property set. 
    
Can you outline the issues/problems you envisage with the CORBA solution?

thanks
Mary
